SPECIFCATION forming part of Letters Patent Nvo. 730,356, dated J' une 9, 1903. Application led August 2,1902 Serial No. 118,076. (No model.)

To all w21/om t may concern:

Be it known that LVITAL ALFRED EMoND, a subject of the King of Great Britain, residing at Quebec, in the county of Quebec, Province of Quebec, Canada, have invented certain new and useful Improvements in Filters, of.r which the following is a specication.

My invention relates to improvements in` iilters, and the object of the invention is to devise a filter in which the water-pressure will not be materially aected and yet provide suiiicient obstruction in the passage of the water to remove all foreign matter therein contained and whereby the :flushing of the filter vessel will be rendered easy, facile, and thorough; and it consists, essentially, of coneshaped outer and inner casings and a basin or sink suitably secured to the outer casing at its lower end, a finishing-valve and reliefvalves, a plurality of sieves and screens, andl a spraying-nozzle designed to iiush an inner screen, the various parts being constructed in detail as hereinafter more particularly described. 1 f Y Figure l is a sectional view of my device. Fig. 2 is a perspective view of the cone-shaped inner casing. Fig. 3'Yis a perspective view of the screen or sieve-cover for the bottom opening into fthe inner casing. Fig. 4 is a perspective view of the cone-screen. perspective view of the screen or sieve-cover for the bottom of the cone-screen.

Like characters of reference indicate corresponding parts in each figure. i

a, is the outer casing, and ZJ andro flanges projecting outwardly and downwardly from its lower end.

d is the basin or sink, preferably of the inverted-cone-shaped type, having the valve c located at the apex of the cone. The sink d is threaded at its upper and outer edge f.

g is a ring inwardly threaded and provided with the overhang or flange lt and the teats i.

7' is an inlet-pipe suitably connected from the water-main to the upper end of the filter.

7a is the inner casi-ng,y designedto fit inside the outer casing a and leave a space therebetween.

Z is a threaded orifice leading from the top of the cone-shaped inner casing 7s and receiving the outlet or water-supply pipe m.

Fig. 5 isa n. and o are projecting rings around the youter casing a in order that the inner casing may not be affected in its position by vibration, andthereby canse too great a strain on the water-supply pipe lm, whichV supports it inits'position inside the outer casing. The

rings fitV and o each have a plurality of perforations 9 and l0 to allow the water to pass therethrough and receive its first screening.

p is a screen suitably attached in the rim q and strengthened by the cross-bars r. The rim q is threaded and is designed to screw into the lower end of the inner cas ing la, which is correspondingly threaded to receive it.

s is a handle designed to facilitate the screwing and unscrewin g of the rim q, carrying the screen p.

if is a cone-screen having a threaded upper end u, designed to screw into a correspondingly-threaded oriiice fc in proximity to the top end of the inner casing it. The threaded orifice leads through the obstructing-wall w, which partitions the chamber a; at the upper end of the inner casing lr. lt will thus be seen that the only openin g up into the chamber a is through the orifice c, leading from the interior of the cone-screen if. v

y is a nozzle having an externally-threaded neck designed to screw into the correspondingly internally threaded opening in the upper end of the cone-screen t. The perforations .e are distributed in the nozzle y so asto have much fewer at its lower end, and consequently the distance between much greater, than through the sides and upper end, in order that a back rush of waiter from the pipe m may be thereby induced to spray from all sides of the nozzle rather than be forced direct through the bottom end. This will insure the cleansing of the conel screen thoroughly on all sides.

2 is a screen or sieve' suitablyT` attached to the rim 3 and further braced and strengthcned by the cross-bars 4f. The rim 3 has its inner periphery threaded and is designed to screw over the rim 5 of the cone t.

6 is a handle to facilitate the attaching and removal of the riin 3, and consequently the screen 2 onto the lower end of the cone i.

too

7 represents relief-valves diametrically opposite one to the other and designed to relieve the filter when under the strain of an extra heavy pressure of Water from the main.

8 represents orifices bored at one or more points through the flange h in order to provide passages for the sweat of' the metal.

l1 is a projecting circular ring or plate at the lower end of the outer cone-casing, firmly secured thereto or forming part thereof.

l2 is a pipe forming a by-pass between the inlet 7' and the outlet-pipe m.

135 is a cock designed to cut out the by-pass and direct the water through the filter.

14. is a cock designed to cut off the filter from the water-supply.

l5 is a cock in the outlet-pipe m and is designed to direct the water passing through the inlet-pipe ,7' and the by-pass l2 into the interior of the cone-screens for the purpose of flushing.

Having explained the various parts involved in my invention in detail, I shall now more particularly explain the 'operation thereof. The water entering the filter from the water-main through the inlet-pipej', at the top of the outside cone-Casin g,iiows down between the outer periphery of the inner casing and the inner periphery of the outer casing and through the perforations 9 and l0 in the rings n and o. The rings n and o, though designed to steady the position of the inner casing, act

valso in the capacities of the first and second screen for the water, preventing any large particles of foreign matter to pass therethrough. The water continues in its course vafter having passed the obstructing-rings and is turned in its iiow at the bottom of the outer casing by the projecting ring or plate ll. The basin or sink d will now fill up and as the pressure of Water continues down between the easings and into the sink it will rise up in the center through the screen p, covering the openv bottom of the inner casing, thus eliminating more of the foreign matter. The water still continues to rise up inside the inner casing la and fills up the cone-screen t, entering through the sides and the bottom screen 2. The obstructing-wall w absolutely prevents any water rising to the chamber except through the nozzle y and the passage e. The continuous pressure of water keeps the filter constantly full and on drawing water from the supply-pipe the circulation through the filter is complete, for the water continues to pass, in the order named, receiving at every stage a still finer screening. A sudden shock from an increased pressure of water from the main is relieved by the valves 7 which are made after any suitable pattern, though shown in the drawings as a simple spiral-spring valve, the said springs having a definite compression regulated to the pressure.

The flushing of my filter is an extremely important matter and is essential to the operation thereof. For instance, to insure the cleansing of the screens and the general flushing of the inside of the inner casin g the water is turned back through the supply-pipe m by suitable connections thereto with the main. The water-supply from the main entering at the top of the outer casing is cut off and the back-flow through the supply-pipe allowed, uninterrupted, to flow into the lter through the chamber c and nozzle y, which has perforations arranged to direct water all over and through the cone-screen 15 and at the same time cleansing the inside of the inner casing 7c. The valve e at the lower end of the basin or sink is opened to allor:r the free passage of the water to the sewer, carrying with it all the dregs and grounds and generally the foreign matter which has been deposited in the bottom of the sink on the outside of the cone t.

rlhe filter is especially adaptable for being set in an ice-box having suitable connections with the main and feed-supply pipes through the said box. This will insure the provision of iced and filtered Water in any part of a building.

In order to take apart my filter, I attach any suitable form o'f key onto the teats il, and by turning the ring g and unscrewing the same it is thus possible to remove the sink to make repairs, if necessary, to the other parts of my device.

This filter may be made of any suitable metal either in castings or metal plates, the system of screens and flushing arrangements being the salient features.

It must be noted that the connections to the main and to the Water-supply pipe are especially arranged so that in case of necessity it will be possible to cut out the filter in the passage, allowing the Water to flow independently from the main to the supply-pipe.

lVhat I claim as my invention isl. In a filter, the combination with an outer casing preferably cone-shaped and a sink or basin surmounted thereby, of a cone-shaped inner casingsuspended therein, a screen or sieve covering for the lower end of the inner easing, a partitioned chamber located at its upper end, a cone screen or sieve suspended from an orifice in the wall of the aforesaid chamber, and a nozzle having a plurality of perforations therethrough, and suspended from the aforesaid orice into the interior of the screen or sieve, suitable inlets and outlets and a flushing-valve at the bottom of the sink, as and for the purpose specified.
